Privacy-focused AI?
Yes, duck.ai
Spoiler alert: it has improved significantly in recent updates.
Duck.ai offers anonymous interaction without requiring an account; you can chat without creating a user or signing in.
The conversations are sent anonymously; identifiers like IP addresses are removed before prompts are forwarded.
Duck.ai does not keep long-term memory between chats: each session is independent and not synchronized across devices.
Text only — there is no voice chat or multimodal capabilities on the platform today.
A mobile app is available for iOS and Android with notifications and better integration than the web version.
The app is not open source; the client and app are not available as open-source code.
Brave browser + VPN is the best option for privacy.
The platform prioritizes actionable, structured responses: lists, steps, and concrete guides rather than vague answers.
Available LLMs include GPT-family models (e.g., GPT-4o, GPT-5 mini), Llama (Meta), Mistral, and Claude (Anthropic); exact model names and availability may vary by region and plan. There is a free tier with basic access and limited model selection, and a paid subscription that unlocks more powerful models, priority in the queue, and additional features.
Recommended if you prioritize privacy and clear responses; consider alternatives if you need synchronized history, voice, or enterprise integrations.
